of the bodies of the vertebr» of fifty spines compiled from various 

 sources to compare with the present spine. A striking feature in this 

 spine is the sudden increase of size at the 7th cervical, and the great 

 relative size of the last three dorsal and first two lumbar. Perhaps 

 the absolute size of the vertebras, especially in the dorsal region is 

 even more striking as the man's height was only 5 feet 7 inches. 

 With the exception of the 3rd, 4th and*öth lumbar, each vertebra in 

 this spine is longer than the corresponding one in the column showing 

 the average. The cervical and lumbar regions both exceed the average, 

 but what is more remarkable is that the eleven dorsal 

 vertebrae exceed the average twelve by 16 mm." (The 

 spaced lines in this quotation were not spaced in the original.) This 

 paper appeared in July 1887. Tenchini published one containing measure- 

 ments of the vertebra' in a case of anomaly in April of the same year, 

 which I did not see till several years later ^). In 1894 -) in the first 

 paragraph of his paper entitled "di una nuova maniera di compenso 

 nelle anomalie numeriche vertebrali dell'uomo", he states that he 

 suspected this compensation as long ago as 1887. It appears there- 

 fore that this idea of compensation occurred to Tenchini and to 

 myself quite independently at about the same time. There is no 

 dispute between us. I have written this only that my contribution to 

 science may not be ignored.
